    The transpeptidase PBP2 governs initial localization and activity of the major cell-wall synthesis machinery in E. coli

    Gizem Özbaykal, Eva Wollrab ... Sven van Teeffelen
    For initiation of cell-wall insertion, the cross-linking enzyme PBP2 stably binds to a component of the cell envelope that is different from MreB filaments.

    Statin-mediated reduction in mitochondrial cholesterol primes an anti-inflammatory response in macrophages by upregulating Jmjd3

    Zeina Salloum, Kristin Dauner ... Xiaohui Zha
    Genetic and biochemical analysis reveals that the anti-inflammatory effect of statins is due to decreasing cholesterol in macrophages and upregulating Jmjd3 to achieve the anti-inflammatory action.

    Quantifying the relationship between genetic diversity and population size suggests natural selection cannot explain Lewontin’s Paradox

    Vince Buffalo
    Quantifying the relationship between census sizes and genetic diversity estimates provides insights into whether natural selection can explain the narrow range of diversity between species.

    Digital wearable insole-based identification of knee arthropathies and gait signatures using machine learning

    Matthew F Wipperman, Allen Z Lin ... Olivier Harari
    Biosensor data collected by digital insoles is comparable to lab-based clinical assessments and can be used to identify subject-specific gait patterns.

    Electrophysiological dynamics of salience, default mode, and frontoparietal networks during episodic memory formation and recall revealed through multi-experiment iEEG replication

    Anup Das, Vinod Menon
    Human intracranial electroencephalography recordings across 177 participants and four diverse episodic memory experiments demonstrate how the anterior insula node of the salience network orchestrates dynamics of large-scale brain networks.

    A conserved RNA degradation complex required for spreading and epigenetic inheritance of heterochromatin

    Gergana Shipkovenska, Alexander Durango ... Danesh Moazed
    Genetic and biochemical studies show that a conserved ribosome biogenesis complex also localizes to heterochromatin, where it triggers RNA degradation and promotes the spreading and epigenetic inheritance of histone methylation.

    Cortico-subcortical β burst dynamics underlying movement cancellation in humans

    Darcy A Diesburg, Jeremy DW Greenlee, Jan R Wessel
    Burst-like neural activity in the β-frequency band conveys inhibitory commands within long-proposed cortico-subcortical networks for motor inhibition, with inhibitory activity in STN preceding thalamic activity, which has strong implications for movement disorders marked by abnormalities in β-bursting.

    Chemokine expression profile of an innate granuloma

    Megan E Amason, Cole J Beatty ... Edward A Miao
    A successful innate granuloma requires CCR2 to organize the macrophage ring, and without CCR2, mice succumb to Chromobacterium violaceum infection.

    Mitochondrial flashes regulate ATP homeostasis in the heart

    Xianhua Wang, Xing Zhang ... Heping Cheng
    Mitochondrial flashes counteract the imbalance of ATP supply-and-demand and constitute an auto-regulator of ATP homeostasis in the heart.

    Intracellular growth of Mycobacterium tuberculosis after macrophage cell death leads to serial killing of host cells

    Deeqa Mahamed, Mikael Boulle ... Alex Sigal
    The rapid killing of macrophages by Mycobacterium tuberculosis aggregates, and the subsequent proliferation of the bacteria inside the dead cell, leads to a cell death cascade and explains the coupling of necrosis and pathogen growth observed in active disease.
